Clinical Excellence

As specialist members of the American Association of Endodontists, our expert team, led by respected endodontic specialists Dr. Dewsnup and Dr. Bennett, includes an experienced endodontic staff. We provide the highest standard of professional care in a friendly, comfortable environment.

Left untreated, your cavities can result in significant pain, the formation of abscesses, and the ultimate need to have the tooth extracted. While there are multiple steps on the way to losing your tooth, you can halt them in their tracks by avoiding cavities altogether.
Dental Abscesses
There are a variety of common symptoms that can be identified when abscesses are present. While many of them can be the result of other conditions, when multiple of them occur together, the odds that you’re dealing with an abscess go up.
During a root canal, the tooth is opened and the pulp removed. Biocompatible cement is used to fill the tooth before it is restored with a crown or other restoration.
Endodontists frequently treat patients who are experiencing sudden and severe pain due to damaged or diseased teeth. Some of the most common endodontic emergencies pertain to cracked teeth, badly infected teeth, and inflamed or infected bone tissues beneath the gums.
A root canal could also be the right treatment for you if you prefer to preserve as much of your natural tooth as possible instead of extracting both the healthy and diseased portions of your tooth.
